Cored wire technology generally refers to cored wire manufacturing technology and cored wire application technology. It firstly breaks various additives (such as spheroidizing agent, inoculant, creeping agent, desulfurizer, deoxidizer and modifier) into a certain particle size, wraps the core wire with steel belt, and then adds the core wire into the metal liquid to be treated by means of a wire feeding machine. With the melting of the steel skin, the additives are brought into the metal liquid and react accordingly, the external process can realize computer control and automatic feeding.
Production characteristics of spheroidizing agent and vermicular agent: automatic batching, medium frequency furnace melting, water-cooled metal solidification. Pure lanthanum, heavy rare earth magnesium, nickel magnesium, nickel magnesium silicon, ferrite, pearlite and other spheroidizing agents.
High purity, less impurities, easy to melt, low addition temperature, low addition amount, high yield, low cost, can purify the alloy melt, improve the casting and deformation properties of magnesium alloy, refine the grain and modify the alloy structure. It can effectively improve the anti-hydrogenation and creep properties and other mechanical properties of magnesium alloy materials, improve the heat resistance of the alloy, and improve the corrosion resistance of the alloy.
The chemical composition is stable, the quality deviation is small, the graphitization core is increased, and the graphite is refined. Promote gray cast iron to obtain A- type graphite, promote ductile cast iron graphite roundness, improve the spheroidization level, and improve the spheroidization rate. Reduce the tendency of white mouth, improve cutting performance, reduce the sensitivity of casting wall thickness, and make the organization uniform.
It does not contain titanium, so there is no need to worry about the pollution of titanium to other materials caused by the mixing of different furnace materials. The white mouth tendency is low. As long as it is not "over-treated" (no excessive amount of vermicular agent is added), inoculation treatment is not required after the vermicular treatment of iron liquid, so as to avoid the phenomenon of "inoculation and ball promotion" and obtain a stable vermicular rate; no matter what kind of sulfur content of molten iron can be made of vermicular graphite cast iron with stable creep rate, stable chemical composition, stable alloy reaction during treatment, suitable for different wall thickness of different materials of vermicular iron castings.
The base material has high refractoriness, no sintering, clean charging material, high calorific value, and the temperature peak value can reach above 1600°C. Strong thermal insulation, 2.55-2.9 times longer than the solidification time of sand riser with the same size, 50-75% reduction of molten metal for feeding, and improvement of process yield; The air permeability is high, and the top of the riser is provided with vent holes so that the gas in the cavity can be discharged smoothly during pouring;
